A Washington Final Order On Petition To Disprove Parentage of Presumed Parent is a court order issued by a court in Washington State that formally disproves the presumed parent-child relationship between a presumed parent and a child. It is typically issued in cases where the biological father of the child is unknown or not legally established. The Order will generally contain the names of the parties involved, the name of the child, the dates of birth of the parties, and the name of the court which issued the order. It may also include additional information, such as any relevant evidence which was presented at the hearing. There are two types of Washington Final Order On Petition To Disprove Parentage of Presumed Parent: 1. Default Final Order — if the presumed parent does not appear at the hearing, the court may issue a default final order in which the parentage of the presumed parent is disproved. 2. Contested Final Order — if the presumed parent appears at the hearing and contests the petition, the court may issue a contested final order in which the parentage of the presumed parent is disproved.
